SPECIFICATION forming part of Letters Patent No. 682,429, dated September 10, 1901.

Application filed April 13, 1901. Serial No. 55,606. (No model.)

To whom it may concern:

Be it known that I, EPPA H. RYON, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Looms, of which the following is a specification.

My invention relates to a take-up or winding mechanism for tape, ribbon, &c., adapted to to be used on what are termed narrow-ware looms, which weave narrow-ware goods, as tape, ribbon, (he.

The object of my invention is to provide a take-up or winding mechanism of simple con- [5 struction and operation and which may be combined with and used on narrow ware looms of ordinary construction and by means of which the tape, ribbon, or other goods woven on the loom may be wound up in a narrow roll on a spool while the loom is in operation, and particularly to provide means for retarding the rotation of the windingspool and the lateral movement or'travel of the tape-guiding needle or guide as the wound tape on the spool increases in size and for equalizing the retardation of the spool and the needle, as will be hereinafter described.

In my take-up or winding mechanism 1 employ a guide, extending in this instance over 0 the spool upon which the tape is wound, having holes therein through which the tape passes before passing to the spool. The needle or guide has a lateral or transverse motion or travel in the direction of the axis of 3 5 the spool on which the tape is wound to carry the tape back and forth on the spool in the direction of its length as the tape is wound thereon by the revolution of the spool. The width or thickness of the wound tape is governed by the amount of travel or movement of the needle. As the tape is wound on the spool the wound tape is constantly increasing in size, and therefore the speed at the outer surface of the Wound tape is constantly increasing, and if the spool was fast on a uniformly-driven shaft this speed would be so great that the tape could not be supplied from the loom fast enough. In order to overcome the increasing speed of the wound tape '50 on the spool, I provide means, preferably in the form of a friction device, which will allow the rotation of the spool on which the tape is wound to be retarded as the wound tape increases in size. It is necessary that there should be more retardation of therotation of the spool the more the wound tape increases in size, so that the take-up of the tape and the let-off of the warps forming the tape shall be always equal. It is also necessary that the speed of the guide which guides the tape as it travels laterally on the surface of the wound tape should be retarded as the wound tape increases in size.

I have shown in the drawings sufficient portions of a take-up mechanism on aloom with my improvements combined therewith to enable those skilled in the art to which my invention belongs to understand the construction and operation of the same.

Referring to the drawings, Figure l is a side view of a take-up or winding mechanism looking in the direction of arrow a, Fig. 2. Fig. 2 is a section on line 2 2, Fig. 1, looking in the direction of arrowb, same figure. Fig.

3 is a sectional detail of the retarding or friction mechanism, taken at a point indicated by line 3 3, Fig. 1, looking in the direction of arrow 0, same figure; and Fig. 4 is a plan view of the tape-guide needle detached.

In the accompanying drawings, 1 is the loom side or frame.

2 is the breast-beam over which the tape 3 passes after it is woven in the ordinary wayon the other parts of thelooni. (Notshown in the I drawings.) The tape 3 passes under the large rotary roll 4, which is fast on a square shaft 5, havingajonrnal or end 5',mounted in bearings 5 on the loom-frame 1, and then up between the roll 4 and the roll 6, and over said roll 6, which bears on the roll 4 and is mounted on the stud 7, having bearings in the arms 8 of the swinging or pivoted frame 8, having studs 9 extending loosely in open-end slots or recesses 10 in the bracket 10, fast to the under side of the breast-beam 2. The tape 3 passes 5 over the roll 6 and under the flanged collar 11, having two flanges 11 thereon, between which the tape 3 passes. The collar 11 is loose on a longitudinal sliding or movable shaft 12 and is held in position thereon to have a ro- 10o tary motion by collars '12, fast on the shaft 12. The collar 11 has an extension 11 thereon in the needle 13, and thetape 3 passes under to the lower surface of which is secured, by screws 13 or'otherwise, the guide-needle 13, which extends in this instance over the spool 14 on which the tape3is wound. The guideneedle 13 at its free end rests on the woundtape and is raised as the tape is wound on the spool 14. There are two holes 13 and'13 the collar 11 and under the guide-needle 13 and up through the openings 13" and then down through the openings 13 to be wound on the spool 14.

15 is a driven shaft journaled in a hub 16 on the stand 16, secured to the loom side. On the inner end of the shaft 15 is fast a pinion 21, which engages the gear 22 on the stud 23, secured in the loom side. Also on the stud 23 is a pinion 24, (shown by dotted lines inFig. 1,) which engages the large gear 25, fast onthe journal 5 of the roll4, to communicate'rotary motion to said roll 4 'in the direction of arrow d, Fig. 2, and advance the tape around said roll and over the roll 6 as fast as it is supplied by the let-off motion on theloom. On the inner end of the stud 23 is the pinion 27, which engages'the gear 28, fast on the'shaft 29, which has its bearing in an open-end slot 30 in the stand 30, secured to the loom side. The three pinions or gears 22, 24, and 27 are fast together, but loose on the stud 23.

Fast on theshaft 29 is the collar 31, whichis encircled and engaged by the curved ends 32" on the two oppositely-arranged jaws or clamps 32, forming in this instance the retarding or friction mechanism above referred to. The twojaws 32 are held in frictional engagement with'thecollar 31 on the shaft 29 by means of a bolt 43 extending loosely through openings in the jaws 32 and having a spiral spring 44thereon intermediate one jaw 32 and a nut-45 on the threaded end of the bolt 43. (See Fig. 3.) The screwing on of the nut 45 on the bolt- 43 compresses the spring 44 and increases the friction of the jaws 32 on the collar31, but allows the jaws 32 to slip on the collar 31 as it revolves between them. Thescrewing off of the nut 45 allows the spring 44 to expand to diminish the friction of the jaws32 on the collar 31. The two jaws 32 are pivotally mounted on a stud 33, fast in.the upper end of an arm 34 on the side of the gear 34, which gear is fast on a longsleeve 35, loosely mounted on the shaft 29. The-spool14 is fast on the slecve 35. The turning of the shaft 29 through gears 27 and 28 operatesto turn the sleeve 35, and spool 14 through the jaws 32 engaging the collar 31, said jaws, as above stated, being pivoted on the stud 33 on the arm 34 on the gear 34, fast on the sleeve 35.

On ashaft 36, secured to the loom'side, is loose the grooved cam 38, having a hub 38 th'ere onon which is fast the gear 39. Said gear '39 is engaged by thegear 34, fast on the sleeve'35 above described. The turning of the gear 34 as above describedoperatcs to turn the gear 39 and grooved cam'38. In the groove 38 of the cam 38 travels a pin 40 on an arm 40, fast on thelongitudinal moving shaft 12. An arm 41, fast on the shaft 12, near its end, bears against a stud 42 in the loom side to hold the pin 40 on the arm 40 in thegroove 38 in the cam 38. The revolution ot'the gear 34, through gear 39, grooved cam 38, and arm 40, causes the shaft12 to have a reciprocating longitudinal motion and the collar 11 thereon and needle 13 to have a lateral travel or motion in the direction of the axis of the spool 14 to guide the tape asitis wound on the spool.

It will be seen that by the operation of the take-up mechanism through the rotation of the driven shaft 15 as the tape 3 is wound on the spool 14 by the revolution of said spool and the travel of the guide-needle 13, as above described, the circumference or size of the wound tape gradually increases, but the supply from the loom remains constant, and therefore the rotary motion of the spool 14 must be retarded. This is accomplished by adjusting by the nut 45 011 the bolt 43 the friction between the jaws 32 and the collar 31 on the shaft 29, so that the ends 32 of the jaws will slip on the collar 31 under sufficient strain. The slipping of the jaws 32" on the collar 31 will be constantly accelerated as the wound tape 011 the spool 14 increases.

The gear '34, operated through thefriction device, as above described, operates the gear 39 andthe grooved cam 38, so that the rotation of said cam 38wi1l be retarded proportionately to the retarding of the rotation of the spool 14, and consequently the lateral movement or travel of the guide-needle 13, operated by said cam 38, will be proportionately retarded.

It will be understood that there will be a series of spools 14 and guide-needles 13 extending across the loom in case of my improvements being used on narrow-ware looms of ordinary construction, and the movement of all of them will be governed by the friction or retarding mechanism, which'is preferably of the construction shown in the drawings and above described, but may be of any suitable construction.

It will be understood that the details of construction of my improvements may be varied if desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
